Question about Keywords?

[kenteck]

Hello

What is a more popular keyword one that ends in plural or not.
ie. Car Part or Car Parts

Both keywords give different results. In Google.

Overtures keyword count for the month says car part is the higher count, But when you enter car parts the plural does not come up.

So how do you figure which is a more popular keyword?

Thanks

Overture combines plurals with the singular (bloody annoying).

I usually start an Adwords campaign with both the singular and plural - its will cost a couple of dollars but will give a clear picture of which one is more popular.

BUT, with stemming being used by Google, it is not as important as it used to be.
